IMPLEMENTASI API CONSUMER PADA SISTEM PKN (PRAKTEK KERJA NYATA) BERBASIS WEB MENGGUNAKAN METODE PARSING JSON

Good integration in building a good system is of course very necessary, in developing a system that can run functionally. This needs to be considered between the back-end and front-end in system development. The Faculty of Engineering is one of the faculties at the University of Muhammadiyah Ponorogo that implements a lecture management system in the form of digital-based PKN. In addition, to make it easier to develop this system, a separation of concern is applied, which is a principle of separation between custom algorithm rules and views. However, in the integration process, this is certainly something that needs to be considered, because the programming language used between the back-end and front- end may be different. An API (Application Programming Interface) is required by the front-end and back-end to bridge the two. The data exchange format generated by the API can be in the form of json or XML, but the front-end needs to convert data that is still in JSON format into an object that is used by the front-end using the JSON parsing method. The result of this research is that it can produce a well-integrated system that runs according to functionality.
